Abstract

Information on the type, nutritional value, and use of local forage as racehorse feed remains limited due to the lack of exploration and identification of available local forage germplasm. To develop competitive livestock, it is necessary to utilize local resources that have added value, such as local forage with good nutritional quality adapted to local climate conditions. Research aimed to determining the nutritional composition of forage feed for racehorses in Empang District, Sumbawa Regency was analyzed from 27 June to 27 July 2022 at the Animal Nutrition and Feed Science Laboratory, Faculty of Animal Husbandry, Mataram University. Samples of forage were taken from predetermined locations and then it dried to analyzed. The samples were taken randomly from 10 percent of total population of racehorse breeders. This research presents descriptive discussion of the qualitative data obtained. It analyzed quantitative data using the Microsoft Excel program, based on mean and standard deviation. The results indicate that the Sumbawa Racing horse feeding system involves directly providing six types of feed with varying nutritional content to the horses in their stables.. They are such as Bermuda Grass (Cynodon dactylon) with nutritional composition: DM 23.54%; CP 12.02%, TDN 43.59%, Kekawatan grass (Cynodon nlemfuensis): DM 29.38%; CP 8.66%; TDN 36.44%. Deccan grass (Echinochloa colona): DM 29.26%; CP 7.64%; TDN 39.37%. Mung bean straw (Vigna radiata): DM 89.72%; CP 7.58%; TDN 39.00%, Rice bran (Oryza sativa): DM 89.95%; CP 8.75%; TDN 62.04%, and Corn grain (Zea mays): DM 24.67%;C P 6.92%; TDN 45.07%.

Abstract

Pari Island is one of the islands among the Thousand Islands group, about 46.32 km from the center of Jakarta with a total area of 310,000 km2 has high biodiversity, one of which is from the macroalgae group. Although macroalgae are a source of high biodiversity, the utilization of macroalgae is still very minimal to do because of the lack of education in the community about the types and benefits of macroalgae found in waters. This study aims to determine the diversity of macroalgae in Rengge Beach, Pari Island, Kepulauan Seribu, Jakarta so that later the community can find out more information about the types, characteristics, and potential utilization of macroalgae. The research was conducted in December 2022 using the benthic belt transect method with a total of 5 stations, carried out by drawing a line from the shoreline inland with a transect length of 100 m and a width of 10 m (5 m to the right and left sides), a monitoring area of 1 km² (10x100 m) between stations. Samples were taken and identified to the species level at the Plant Structure and Development Laboratory, Biology study program, Jakarta State University, Jakarta. Observations include several characteristics both morphologically and anatomically. The results showed that there were five species of macroalgae that could be identified, namely Halimeda sp, Gracilaria sp, Turbinaria sp, Padina sp, and Sargassum sp, therefore it can be concluded that there are only five genera of macroalgae in this place. This research needs more development that can provide more benefits, one of which is to develop the research area and further identify the types of macroalgae obtained to find out more specific information about the potential of macroalgae.

Abstract

West Nusa Tenggara (NTB) is one of the provinces that cultivates many Pinctada maxima pearl oysters. Seed dispersal is a stage that can influence the growth and activity of pearl oysters because they will be moved from the hatchery to the sea. The use of appropriate containers in pearl oyster seed dispersal very necessary to prevent pearl oysters from being carried away by currents or attaching biofouling as a nuisance to biota. The aim of this research is to determine the effect of rearing containers on the growth and survival of pearl oysters (Pinctada maxima). This research used an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used are different types of keeping containers, namely using traditional containers, pocket baskets, waring baskets and lantern baskets. The results of the research showed that rearing pearl oyster spat (Pinctada maxima) for 60 days in Ekas Bay with the influence of different containers showed that the average absolute length growth obtained was 1.80-3.88 cm, the absolute weight ranged from 12.3 -31.10 g and survival rate 38.86 – 83.30%. The conclusion from this research is that using pocket baskets is better than other containers.

Abstract

Porang (Amorphophallus muelleri) is a tuber plant that contains the compound of glucomannan which has high economic value with a number of benefits, including as an industrial raw material. The glucomannan content of porang tubers has received special attention in research, including field research to determine soil properties that influence growth and content of gucomannan in porang tubers. A field survey has been carried out to determine the physical properties of soils that influence the glucomannan content of porang tubers grown in four clusters of agroforestry in the dry land of North Lombok, Eastern Indonesia. The results of the research showed that the physical properties of the soil that had a significant effect on the glucomannan content of porang tubers were soil bulk density (BD) with an R2 value of 53.15%, soil porosity with an R2 value of 60.23%, and silt particle fraction with an R2 value of 23. 47%. Thus, managing soil physical properties to facilitate the better quality of porang tubers is necessary.

Abstract

Semen quality is one of the most important factors for the success of artificial insemination. The quality of the diluent really determines the quality of the liquid semen. Therefore, research to find the most optimal diluent to maintain the quality of liquid semen, whether stored at room temperature, cold or frozen, is continuously being carried out. The aim of this research was to determine the motility and viability of Boer cross goat spermatozoa in Tris albumin extender supplemented with fig fruit filtrate and stored at cold temperatures. This study used a completely randomized design (CRD) with 4 treatments, namely P0 (standard Tris extender + 2.5% egg yolk), Pl (Tris standard extender + 2.5% albumin), P2 (P1 + 4% fig fruit filtrate), and P3 (P1+6% fig fruit filtrate). Evaluation of fresh semen includes volume, color, aroma, consistency, degree of acidity (pH), mass motility, individual motility and spermatozoa viability. The variables observed in this study were individual motility and spermatozoa viability up to a minimum motility limit of 40%. The results showed that the addition of fig filtrate to the Tris-albumin based extender did not increase the ability of the extender to maintain spermatozoa motility and viability compared to the standard Tris-egg yolk extender. In conclusion, the addition of fig fruit filtrate to the Tris egg albumin extender had no better effect than the standard Tris-egg yolk extender. To get better results, further studies are needed on various concentration combinations between albumin and fig fruit filtrate in Tris-albumin based.
